WATER OR HYDRAULIC ENGINE.

SPECIFICATION forming part of Letters Patent No. 673,914, dated May 11901- Application filed January 5, 1900. Serial No. 442. (ModeL) T0 aJZwhom it may concern.-

Be it known that I, ALBERT LEGG, a citizen of the United States ofAmerica, residing in the town of Allendale, county of Bergen, and Stateof New Jersey, have invented certain new and useful Improvements inWater or Hydraulic Engines, of which the following is a specification,reference being had therein to the accompanying. drawings.

My invention relates to water or hydraulic engines; and its object is toprovide means whereby power may be developed from a fall of water at ornear the top of the fall and whereby power may be developed from thepull of the water instead of from the push thereof, as is usual in mostWater-engines and water-wheels.

To this end my invention consists of a device comprising a tube or pipecommunicating at its upper or supply end with two upright hollowcylinders, combined with devices connected with said cylinders uponwhich the water supplied to the tube may operate and means oftransmitting the power developed by said devices to the revolving shaft.

An application of my device is illustrated in the accompanyingdrawings,in which similar figures of referenceindicate similar parts throughoutthe various views, of which- Figure 1 is a plan view. Fig. 2 is asectional view on the line 2 2 of Fig. 1. Fig. 3 is a sectional View onthe line 3 3 of Fig. 4, and Fig. 4 is an enlarged side view of theworking parts.

1 represents a body of water, as a creek or river.

2 represents a dam adapted to divert the water 1 into the reservoir 3when the gates 4 thereof are opened.

5 is a dischar e-pipe sufficient to properly accommodate the amount ofwater coming into the reservoir 3 through the gate 4. At the upper endof discharge-pipe5 are two up right hollow cylinders, respectively 6 and7.

8 is a support for the shaft 9, upon which are two cranks l0 and 11.Operatively connected with crank 10 is a rod 12. Set upon said rod 12 isan abutment 14, which may be held in place by aset-screw, as shown inFig. 3.

13 is a cover sufficient to cut off the supply of water to the pipe 5through cylinder 6 when the same rests upon the top thereof and isloosely mounted upon said rod 12, so that when said rod 12 rises withcrank 10 the abutment 14: will carry said cover 13. Said abutment 14.should be adjusted so that when the rod 12 is at its lowest limit ofstroke the abutment 14 will be clear of the cover 13. Any convenienthearing, as 15, may be provided, whereby said rod 12 is guided so thatcover 13 may reciprocate down upon and up from the top of said cylinder6.

Operatively connected with crank 11 is rod 16, hearing at its lower enda piston 17, working in said cylinder 7.

18 is a wheel upon shaft 9, operating to balance the device, and 19 isthe supportingframework. If the wheel is turned so that the cover 13 israised and water is allowed to enter the reservoir in quantitiessufficient to maintain the water in the reservoir at or about the levelof the cover 13 at its highest limit of stroke, the force of the waterfalling through cylinder 6 and discharge-pipe 5 will pull said coverdown and the wheel 18 will thereafter continue to revolve so long as thesaid proper supply of water is maintained.

What I claim, and desire to secure by Letters Patent, is

1. A water or hydraulic engine consisting of a pipe arrangedto carrywater from one level to a lower one, communicating at its upper end witheach of two upright hollow cylinders, a piston adapted to operate in oneof said cylinders, a cover adapted to close the upper end of the otherof said cylinders, a revolving shaft having two cranks thereon, meanswhereby, as said piston descends, one of said cranks is pulled down, andwhereby as said cover descends the other of said cranks is pulled downthrough a part of itsdownward stroke, and'means of maintaining water atany desired level above the upper ends of said cylinders, substantiallyas described.

2. In a water or hydraulic engine, the combination of a pipe adapted tocarry water down from one level to another, two upright hollow cylinderscommunicating with said pipe at the upper end thereof, a piston adaptedto operate in one of said cylinders, a cover adapted to close the upperend of the other of said cylinders, a revolving shaft having two cranksthereon, means whereby said piston as it descends, pulls down one ofsaid In Witness whereof I hereunto affix my name,

cranks, means whereby saidcover as it dein presence of two witnesses,this 3d day of scends pulls down the other of said cranks through a partof its downward stroke, and January, 1900. means of maintaining Water,at any desired 5 level above the upper ends of said cylinders,Witnesses:

with a balance-wheel mounted on said shaft, J. B. MAXWELL,

substantially as described.
